For more than twenty years Click Clack has been a leading company in the design and manufacturing of quality airtight storage. Click Clack Kitchen Essential containers are airtight, provide easy access to contents, and are unmatched for convenience. Items in Click Clack's Kitchen Essential range are a unique rectangular shape, stackable and ideal for kitchen cupboards, pantries, and offices. The lid opens with a single- handed fingertip flip of the toggle: Click to open, Clack to close. The base is made from strong, clear polystyrene and allows for easy content identification. Kitchen Essentials come in eight different sizes and are BPA free. To clean, hand wash the base with a non-abrasive cleaner and wipe lid with a damp cloth. Allow both parts to dry completely before reassembling. Note: the Kitchen Essential Collection was formally known as the Storer Collection.
